1. Exhaust extruder.
2. Recycling of process gases.
3. Vacuum suction treatment in food industry.
4. Vacuum pouring in beverage industry.
5. Vacuum separation of isoboiling mixtures.
6. Purification and special drying treatment of pharmaceutical industrial products.
7. Gas evacuation in bottle before injection of high purity gas.
8. Reduction of solutes, such as drying, filtration, crystallization and distillation.
9. Laboratory Vacuum and Aircraft Manufacturing Factory Laboratory Vacuum. With or without compression of the pumped gas in the working chamber, the limit vacuum is higher and the power consumption is lower.
10. If the disadvantage of using rotary vane pump in all vacuum process reacting with oil is time, we can consider adding a Roots vacuum pump to the rotary vane pump, which can greatly shorten the pumping time. The goal is to develop and reduce power consumption.
11. Installed in the pump housing, there is a certain gap between the screw and the screw, so when the pump works, there is no friction between the screw and the screw, the operation is stable, the noise is low, and the working chamber does not need lubricating oil, so it can remove the gas occasion containing a large amount of steam and a small amount of dust.
Screw vacuum pump in the pump shell as a synchronous high-speed reverse rotation of the suction and exhaust effect of the pumping equipment, it is an alternative product of oil-sealed vacuum pump, in the face of the problem of vacuum pumping, we should do a good job before use, to avoid maintenance.
